Cobalt; remember, you are on probation. NO KNIFE PURCHASES, REMEMBER??
Cliff; I read your review with interest; frankly, I was surprised that the knife steel performed as well as it did.
After all, VG-10 is basically 440C with half the Manganese removed, and 1.5% Co, and 0.3% vanadium added. That doesn't impress me much at all. Remember that the difference between ATS-34 and BG-42 is the addition of 1.2% vanadium to the ATS-34 composition. Here, you are adding only 10% as much V as BG-42 has.
Look at VG-10 in another light; it is basically BG-42, with 90% of the vanadium removed, 75% of the molybdenum removed, and 1.5% Co added.
These changes seem somewhat difficult to understand; it seems to me that they are trying to make a tool steel, along the traditional lines, with W, V, and Cr carbides present (there is no W in VG-10, but my point is that there is often W in tool steels). Therefore, removing 90% of the V doesn't make much sense to me.
If you want a super tool steel, take a look at this:
V 4.90 W 12.00 (that is correct, 12%)
This steel has more goodies than VG-10 ever dreamed of having. Further, the goodies are in higher concentrations. Except for the Cr. But what purpose does the Cr serve? Is VG-10 an attempt at a stainless tool steel? If so, I will take BG-42, thank you.
However, these are the thoughts of a person who deals with these matters on a theoretical level. What really counts is how the blade actually performs. Cliff, any idea on why it performs so well, despite seemingly no compositonal reason for doing so?? Onward through the fog. Walt
